Key Takeaways
The February TaiyangNews TOP SOLAR MODULES listing features 40 products from 33 companies, one fewer than last month
JA Solar and Tongwei Solar move up to 4th position, having updated their TOPCon module efficiencies to 23.7%
Another PERC product has been delisted this month, with Suntech phasing out its product offering
The TOP SOLAR MODULES February 2026 edition is the 50thedition since we started this initiative 4 years ago to track the top efficiencies of commercially available modules from leading integrated manufacturers. Following an HJT product efficiency update and a few delistings in the the January edition, the current edition includes 2 TOPCon product efficiency updates and 1 PERC delisting.
JA Solar and Tongwei Solar have updated their TOPCon module efficiencies this month, and their product rankings have risen as a result. With this update, JA Solar and Tongwei move from their 7th and 17th positions, respectively, to share the 4th position in this edition. These updates are in line with the trend observed in overall TOPCon efficiency improvements in TaiyangNews’ TOP SOLAR MODULES over the past few months.
On the downside, the list shrinks once again by 1, following the delisting of a PERC-based product from Suntech.
Badge of Excellence
As part of the TOP SOLAR MODULES feature, we have a new list of efficiency leaders for the year 2025, highlighted through the TaiyangNews Badge of Excellence released in December 2025. As part of the TOP SOLAR MODULES Analysis Report 2025, summarizing the findings from an analysis of 24 editions published throughout 2024 and 2025, we announced the names of the companies that are eligible for the Badge of Excellence, which was started in 2023. The rules of the game remain the same – manufacturers who have featured in the Top 10 for at least 6 months within a calendar year are eligible to apply for this badge. The winners of the TaiyangNews Badge of Excellence 2025 are: AIKO, Astronergy, DMEGC Solar, Huasun, JA Solar, JinkoSolar, LONGi, Maxeon, Tongwei Solar, and Trinasolar. Compared to the Badge of Excellence 2024, SPIC slipped off the list, while TrinaSolar filled the gap, maintaining the total count at 10.
Background
Efficiency and output power are the 2 key characteristics of a solar module. While there are several ways to improve module power, such as employing larger cell sizes or integrating more cells into a module, it’s the efficiency that truly speaks to the ability of the solar device to convert sunlight into power per area. That’s why this list includes only the highest-efficiency solar modules.
TaiyangNews has been diligently tracking the efficiency progress of solar modules through its annual reports on Advanced Module Technologies, a series that began in 2017. We also provide in-depth coverage of cell and module technology updates in our annual High Efficiency Solar Technologies Conference, the most recent of which took place in December 2025 (access the presentations here).
However, the solar sector is characterized by rapid change, with significant advancements occurring throughout the year. We capture these developments through the various events we organize on different topics. To synthesize this information and provide our readers with frequent updates on global module efficiency progress, TaiyangNews launched this monthly column on commercial TOP SOLAR MODULES at the beginning of 2022.
Furthermore, as mentioned above, TaiyangNews publishes reports analyzing this monthly list, the latest of which was released in December 2025 (see TOP SOLAR MODULES Analysis Report 2025).
Methodology
Before going into the details, here is some background on the methodology and selection criteria: module efficiencies have been improving considerably in recent years. In order to make the list rewarding for technically advanced products, we set 21.5% as the minimum efficiency criterion to feature in the list, and select only commercially available top solar modules from each cell technology stream of a module maker. For example, if a company is offering 2 different product streams based on PERC that have more than 21.5% efficiency, then only the product with the higher efficiency is considered for this list. However, if a module maker offers, for example, products based on PERC and TOPCon with efficiencies of 21.5% or above, then both products are listed. Efficiency is the only criterion for ranking in the list (whenever available in the specs, we have used 2 digits after the decimal point for efficiencies; otherwise, one). However, as we see products with the same efficiency more often, power determines the order of ranking in this case. And when both efficiency and power are the same, we list the manufacturers in alphabetical order.
The list does not distinguish between different module formats. All typical module sizes used in rooftop and ground-mounted solar system applications are included and treated equally, as companies increasingly use larger modules also for rooftop applications.
We only list modules that are based on the manufacturer’s cells produced in-house, which means modules using externally sourced cells are not featured in the TOP SOLAR MODULES list. Having the complete data sheet listed on its manufacturer’s website is the first step for a module to be considered a commercially available product. As such, the efficiency and power data listed here are taken from the datasheet available on the respective company’s website. This also means that any new product announcements without final technical data published are not included in the list, as their module specs often differ considerably from the products that are finally available for purchase, and some products presented at trade fairs do not even see commercial light at all. However, just the existence of an online datasheet generally does not suffice, especially for top efficiencies in the respective technology stream. If module specs listed on the websites appear to have ‘conspicuously’ high efficiencies or new record-efficiency products are announced, we ask for additional proof of commercialization before we include a product in the list.
Starting with January edition, we have incorporated a few changes to our table that is published along with this feature.
The columns are rearranged with cell and module parameters in the order of Cell Tech, Cell number, Cell size (in mm), Module technology, Power (in W), Efficiency (%), and Module size (in mm)
The cell sizes are now represented in 2 dimensions (L x W mm), indicating the size of the final individual cell (1/2 cut, 1/3 cut, etc.) placed inside the module
The sizes for most of them are collected from the manufacturers or product datasheets, while a few are based on our estimations, which are marked with an “*”
Module technology column now features the type of front and rear cover – glass-glass or glass-backsheet –, and eliminates half-cell and MBB, as these are anyway standard
Additionally, the module dimensions column is added to the table
The “wafer type” column is also removed as it is common knowledge that all the latest cell architectures are based on n-type, while PERC represents p-type
Results & Changes
The second monthly edition of this year’s TaiyangNews TOP SOLAR MODULES features 40 high-efficiency products – 1 less than in the previous month – from 33 companies. At the same time, it also features efficiency improvements. JA Solar and Tongwei Solar provided commercialization details for their high-efficiency TOPCon modules, both rated at 23.7%. With this improvement, the 2 companies jump to the 4th place in our listing, sharing the rank with Trinasolar, which solely occupied this position previously. While they share a common efficiency level of 23.7%, . Tongwei earns the first mention given its higher power rating, , followed by JA Solar and Trinasolar in the alphabetical order since their efficiency and power figures are identical. The phase-out of PERC products continues, with the latest coming from Suntech, prompting its delisting from this edition. These changes have also revised the rankings of companies from rank 4 to 19, and then from rank 32 to 38 in the TOP SOLAR MODULES. However, the top 3 ranks from the last edition remained unaffected.
As in the previous editions, AIKO retains leadership with its 24.8% BC module. In the December edition, AIKO provided commercialization details for the module rated at 24.8% efficiency and 670 W from the Comet 2U G660-MCH72Mw product series. Built with 144 half-cells of the M10 format, the module measures 2,382 mm in length and 1,134 in width. It is a monofacial module assembled with 3.2 mm tempered glass on the front and a backsheet on the rear side. The module features a grid-free front design for improved aesthetics and uniform appearance. It uses anodized aluminum frame and weighs 27.1 kg. Similar to most modules, the power degradation in the first year is 1% with an annual degradation of 0.35%, and a power attenuation of 88.85% at the end of 30 years.
Until November 2025, AIKO was represented with a 24.4% module share, which was also the highest at that time. AIKO continues to hold the first position ever since its debut with the ABC series in March 2023, with 23.6% efficiency at that time. It went on to break its own record, achieving 24% in June 2023. It further increased the efficiency to 24.2% with 655 W power in May 2024, with a larger length module of 2,382 mm from 2,278 mm, and then again to 24.4% with 660 W power by commercializing AIKO-G660-MCH72Mw in June 2025.
LONGi ranks 2nd in our listing and is currently represented with a 24.7% efficiency BC module. In December, the company shared proof of commercialization for its latest EcoLife residential product with 24.7% efficiency and 505 W power. This BC module is built on LONGi’s hybrid interdigitated back contact (HIBC) technology, which uses a passivated contact architecture based on TOPCon for one polarity and HJT for another polarity. The technology also underpins the highest crystalline silicon cell efficiency of 27.3%, a current world record in the single-junction category. More details about this technology can be found at LONGi’s recent talk at the TaiyangNews High-Efficiency Solar Technologies 2025.
The listed product is packed with 108 half-cut cells in a 1,800 × 1,134 mm² module area, with a double-glass configuration comprising 2 mm and 1.6 mm glass on the front and rear, respectively. It uses an anodized aluminum frame and weighs 23.5 kg. The power degradation specified for the product in the first year is less than 1%, with an annual degradation 0.35%, and a power attenuation of 88.85% at the end of 30 years.
Till November 2025, LONGi’s best product was Hi-MO 9 with an efficiency 24.2%, and since March 2025, the company has held the 2nd position. This 24.2% efficiency level was first featured in our list in June 2025. At this point, LONGi surpassed Maxeon and has held the 2nd place solely ever since. Before this, in March 2025, LONGi moved up to share the 2nd position with Maxeon after commercializing its Hi-MO 9 module featuring 24.1% efficiency. Before that, LONGi had held the 3rd place since May 2023, when its Hi-MO 6 module improved from 22.8% to 23.2% efficiency.
In January, Risen presented an update, improving the efficiency and power of its module to 23.8% and 740 W, improved over the previously listed 23.5% and 730 W product. Also part of the Hyper-ion Pro product series, the RSM132-8-740BHDG high-efficiency module consists of 132 half-cut cells based on the 210 mm wafer. It has a bifaciality of 90±5% and uses 2 mm double-glass. The module measures 2,384 × 1,303 × 30 mm and offers a 1% degradation warranty in the first year and a power attenuation of 90.3% after 30 years. Risen presented its product and technology advancements at the recent TaiyangNews High-Efficiency Solar Technologies 2025 held in December, which can be accessed here.
Even in the December 2025 edition, Risen increased its module efficiency from 22.5% to 23.5%, a 1% absolute increase, which resulted in a big leap in its ranking from 21st to 6th. This improvement resulted from collective advancements at the cell and module levels. Starting at the cells, the structure features microcrystalline silicon passivation layers on both the front and rear sides. As for advancements in metallization, it features a fine finger width, increasing the light-absorption area. The module is based on a zero-busbar (0BB) interconnection layout.
Risen Energy’s Hyper-ion HJT module, first featured in June 2023, positioned itself at the 7th rank at the time, with an efficiency of 22.5%, and a high power rating of 700 W.
The next position, at 23.7% efficiency, which was previously occupied by Trinasolar, is now shared between Tongwei Solar, JA Solar, and Trinasolar, with Tongwei getting the first mention as it has the highest module power among the 3 products at this efficiency level. Tongwei’s updated TOPCon product, TWMNF-66HD735, features 23.7% efficiency and 735 W power. This improvement is attributed to both cell- and module-level changes. At the cell level, this model features finer finger widths achieved using stencil printing and passivating the cut edges with what Tongwei describes as TPE. It also uses poly fingers on the rear-side. Unlike its predecessor, this model is based on Tongwei’s TNC 2.0 cells of the 210 mm (G12) wafer format, with 132 bifacial half-cut cells. The module dimensions are also higher at 2,384 × 1,303 × 33 mm. It is a double-glass module with a bifaciality of 80±5%. Tongwei presented the technology aspects of TNC 2.0 at the recent TaiyangNews High-Efficiency Solar Technologies 2025, and can be accessed here.
Its previously listed module TWMND-72HS575-590W was rated at 590 W and 22.8% efficiency, placed 17th in the rankings. It was designed with 144 half cells based on its monofacial TNC cells on a 182 mm wafer format. The module featured a 3.2 mm front glass and a white backsheet. It was slightly smaller at 2,278 × 1,134 × 35 mm.
Entering the listing in April 2023, Tongwei improved the top efficiency from 22.5% to 22.8% and power from 580 W to 590 W in February 2024. These improvements enabled its move from 10th place to 6th at the time. However, Grand Sunergy’s entry in October 2024 shifted it down to 7th, with further declines to 10th in November 2024 and 11th following Trinasolar’s May 2025 update. In June 2025, it was pushed to 12th, to 13th in July 2025, and to a further 15th in September 2025. In November 2025, its rank improved to 14th; however, it dropped to a shared 17th in December 2025 and remained there.
JA Solar provided commercialization information for its updated TOPCon module to 23.7% efficiency and 640 W, from 23.5% and 635 W previously. The model JAM66D45 640/LB is based on JA’s DeepBlue 4.0 Pro series. With this update, JA’s rank in this edition has moved up from 7th to 4th. The module measures 2,382 × 1,134 × 30 mm and weighs about 33.1 kg. It is a bifacial double-glass module with a bifaciality of 80±5%, comprising 132 half-cells based on a rectangular M10 wafer platform. Similar to other TOPCon modules from major suppliers, the power attenuation at the end of 30 years is 87.4% with 0.4% annual degradation starting from the 2nd year.
JAM66D45 630/LB was first featured in September 2025 with 23.3% efficiency, and improved to 23.5% in October 2025, also raising the power output from 630 W to 635 W.
Previously, the list featured the JAM72D40 model, which entered in July 2024 at 22.8% efficiency ranking 6th, was raised to 23.0% in November 2024, moving it up to rank 5, and further improved to 23.2% in June 2025 and remained so until it was replaced in September 2025. Before JAM72D40, JA Solar was represented by JAM72D42 630/LB, which had remained unchanged since August 2023 until July 2024.
The next in the list is Trinasolar, with its Vertex N series TSM-NEG19RC.20 module, featuring 23.7% efficiency and 640 W power. A sole occupant of rank 4 earlier, Trina now shares it with both Tongwei and JA Solar. In January, Risen’s rise pushed Trinasolar’s product to 4th in ranking from 3rd in the December edition. Trina’s module is built with 132 half-cells based on 210R wafers. It uses 2 mm glass on both sides and offers a bifaciality of 80±5%.
After a significant improvement in efficiency from 23.2% to 23.7% in November 2025, Trinasolar remained in 3rd position until Risen’s move up in January 2026.
The company was previously represented by the NEG21C.20 module from the same Vertex N series in our listing, from September 2023 until October 2025, with 22.5% efficiency and 700 W of power. It went on to achieve 23% in May 2025 and 23.2% in October 2025. Before the Vertex N series, it was the Vertex S+ series until August 2023 with the same 22.5% efficiency; however, it had a lower module power of 450 W.
Back then, while both product groups had the same efficiency, the former offered a higher power output of 700 W compared to 450 W for the latter. As a result, the company’s ranking among products with 22.5% efficiency rose from the penultimate position to 2nd place in this group in September 2023.
JinkoSolar, with a module efficiency of 23.69%, currently holds the 7th position, down by 2 ranks from the previous edition due to the updates mentioned above. The company had, in fact, improved its module efficiency to 23.69% in December 2025, briefly moving it into 4th place, and then moved down to 5th with Risen’s update in January 2026. The company’s JKM640N-66HL4M-BDV, part of the Tiger Neo series, is a bifacial module built with 132 half-cells based on n-type monocrystalline TOPCon architecture. It incorporates the company’s HOT 3.0 cell design for enhanced light trapping, current collection, and reliability. The module uses 2 mm glass on both sides, achieves a bifaciality of 80±5%, and is backed by a 30-year linear power warranty with only 0.4% annual degradation after the first year.
The company first commercialized its Tiger Neo (JKM625–635N–66HL4M-BDV) TOPCon module in July 2025, with 23.32% efficiency and a 630 W power rating. Until then, the company was represented by a 22.65% product, ranked well below the Top 10. With this major upgrade, JinkoSolar’s ranking jumped sharply from 14th to 5th in July 2025, making it to the top of the listed TOPCon modules, until Trinasolar surpassed it in November 2025.
Within just 3 months, the company further enhanced the module’s performance, increasing efficiency to 23.51% and power to 635 W. As a result, JinkoSolar climbed another step up to 4th place in the October 2025- a significant milestone, as it was the first time a TOPCon module surpassed the top HJT efficiency benchmark within the TaiyangNews TOP SOLAR MODULES rankings. In November 2025, although Trinasolar surpassed Jinko, it remained at Rank 4 with the former replacing Maxeon at Rank 3.
Looking back, the company dropped from 9th to 11th in the July 2024 edition, slipped further to 12th in October, to 13th in May 2025, then to 14th in June 2025, before its major leap to 5th in July 2025 following the introduction of the Tiger Neo series.
Astronergy also drops by 2 ranks to 8th in this edition. With 23.51% efficiency and 635 W power, the company’s ASTRO N7 series product is a bifacial double-glass module built with 132 half-cut TOPCon cells based on 182 mm rectangular wafers. It has dimensions of 2,382 × 1,134 × 30 mm and a bifaciality of 80±5%.
The ASTRO N7 series entered the listing in March 2025 with an efficiency of 23%, replacing ASTRO N5, and improved the company’s ranking from 7th to 5th. In the July 2025 edition, Astronergy further improved the module’s efficiency to 23.1% and its power to 625 W. Despite these improvements, the module’s ranking dropped from 6th to 7th in July 2025, overtaken by JinkoSolar’s jump to rank 5th in that edition. In September 2025, with efficiency reaching 23.3%, Astronergy reclaimed 6th place. However, in the October 2025 edition, it moved 2 steps down to 8th, which it held until November 2025. In December 2025, it jumped to 5th with a module featuring 23.51% efficiency and 635 W power.
Over the past 2 years, Astronergy has progressively improved its module efficiency. The previous ASTRO N5 variant, introduced in September 2023, had its efficiency upgraded from 22.5% to 22.6%, and later to 22.8% by March 2024. By November 2024, the company commercialized a high-power 640 W version with 22.9% efficiency, achieved by increasing the cell count from 144 to 156, which also resulted in larger module dimensions (2,465 × 1,134 × 30 mm).
The next efficiency slot is 23.5%, with a negligible difference of 0.01% to its next higher efficiency product in the listing. With Risen moving up, this efficiency was held by 4 products in January 2026 and was ranked 7th, one lower than the December edition. Now with JA Solar’s update, this efficiency club comprises GCL, Huasun, and DMEGC, all ranking 9th.
GCL System Integration (GCL SI), a subsidiary of the vertically integrated, globally recognized silicon supplier to the solar industry, GCL Group, provides solar modules, battery storage products, and complete PV solutions.
Currently ranking 9th, 2 lower than the previous edition because of the above-mentioned updates, there is no change in GCL’s product in this edition. However, in December 2025, the company furnished commercialization details for GCL-N12/66GDF. While belonging to the same product series as before, it delivers a nearly 1% absolute improvement in efficiency, helping it jump from 19th to 6th place. This product has a rated efficiency of 23.5%, improved from 22.53%, and a power rating of 730 W. The company, however, has not elaborated on the technology improvements that led to this significant gain. The N12/66GDF is a bifacial double-glass module with 132 half-cells with TOPCon technology built on the 210 mm wafer. The module measures 2,384 x 1,303 x 33 mm, weighs 38.3 kg, and offers a bifaciality of 80±5%. The power attenuation at the end of 30 years is 87.4% with 0.40% annual degradation from the second year onwards.
The NT12/66GDF was first introduced in June 2025 with 22.53% efficiency, replacing the GCL LOTUS series module with 22.3% efficiency. This upgrade has improved the company’s ranking from 28th to 17th. This module moved to 19th in the September 2025 edition, and dropped another rank to 20th in October 2025. It moved back up to 19th place in November 2025. As mentioned above, in December, there was a significant jump to rank 6. It moved down a rank to 7th in January 2026 with Risen’s update.
GCL SI first debuted in our listing in July 2023 with 2 modules from its GCL GEMINI series – one based on TOPCon and the other on PERC technology. In April 2024, the GEMINI TOPCon module was replaced with a GCL LOTUS series module, although the core specifications remained unchanged. In October 2024, this product dropped from 28th to 29th, tying with Qcells for the rank. GCL SI regained the 28th position in January 2025, as the number of companies at this position fell from 3 to 2 following REC’s move up. GCL SI’s PERC product was delisted in December 2025 as it is no longer available on its website.
Huasun is the second joint holder of the 9th rank. The company features the Himalaya series HS-210-B132DS730W module with an efficiency of 23.5% at 730 W. The module comprises 132 HJT half-cells based on the 210 mm wafer. It is a bifacial module with 2 mm dual-glass, measuring 2,384 × 1,303 × 33 mm and weighing 36.5 kg.

It features dual-glass construction, offers up to 85% bifaciality, and comes with a 30-year linear power warranty, similar to other TOPCon players.
DAH Solar made its debut in the TOP SOLAR MODULES list in September 2025 at the 9th rank with the same product as it is currently listing. Headquartered in China, the company is well known for its balcony solar kits and its patented Full-Screen module design, which eliminates the front frame to reduce dust accumulation. In the October 2025 edition, following various efficiency upgrades, DAH Solar’s ranking moved to 11th, 10th in November, and 13th in December 2025.
With the recent round of module upgrades, most manufacturers have moved beyond the 23% efficiency range. The 23% band, previously shared by Trinasolar, Tongwei Solar, and DMEGC Solar, is now represented solely by Tongwei Solar, which continues to rank 15th in the current edition. The company is represented by its TWMHF-66HD715W HJT module, based on its proprietary HJT cell technology, called THC. It features 23% efficiency and a power output of 715 W, built with 132 half-cells of the 210 mm format. The company presented the details of its current technologies and future technology roadmap at the TaiyangNews High-Efficiency Solar Technologies 2025 Conference, and they can be accessed here.
Represented only in the TOPCon and PERC segments until November 2023, Tongwei Solar’s HJT product entered our listing with a 715 W module in December 2023 at the 4th rank. It then moved to 5th in May 2024 and to 6th in June 2025. With the inclusion of this HJT product, Tongwei became one of the few companies to have featured simultaneously in all 3 different technology streams in our listing. However, the delisting of its PERC module in September 2024 narrowed its representation to 2 streams.
Jetion Solar’s product, also based on HJT technology with 22.9% efficiency and 710 W power output, ranks next, 16th, down from 15th in the previous edition. Its JT SLk(B) model is a dual-glass, bifacial module built with 132 half-cut monocrystalline cells based on the 210 mm wafer format. It measures 2,384 × 1,303 × 33 mm and weighs 36.4 kg. The module offers a bifaciality factor of approximately 90±5% and utilizes 2.0 mm high-transmission, AR-coated tempered glass on both sides.

Jetion Solar joined the listing in June 2025 at the 10th position with its HJT module, featuring a rated maximum efficiency of 22.9% and a power output of 710 W. While these technical specifications remained unchanged, its Top 10 debut, however, was short-lived – being pushed to 11th in July 2025 due to efficiency improvements by other manufacturers. It later moved to 13th in September 2025, then up to 12th in November, and then back to 15th in December 2025 due to the efficiency improvements above.
Grand Sunergy, a China-based manufacturer specializing in HJT cell manufacturing, has moved down by a rank to 17th, for its HJT module, which has a 22.86% efficiency and a 710 W power rating. The company first entered our list at 6th place in October 2024 with this module called GSM-MH3/132-BHDG710, built with 210 mm wafers to ultimately measure 2,384 × 1,303 × 33 mm in size and weigh 38.5±0.5 kg. The PV panel is rated at 85% bifaciality and includes a 30-year linear power warranty. While these specifications have not changed, the product's position has seen changes due to the other upgrades.
In November 2024, efficiency updates from JA Solar and Astronergy led to a drop in its position to 8th, followed by another shift to 9th in March 2025. With Trinasolar improving its module’s efficiency in May 2025, the module moved down to 10th. Jetion Solar’s entry in June 2025 pushed it further to 11th, and another place to 12th in July 2025, following efficiency gains from JinkoSolar and Astronergy. With more efficiency improvements from other companies in the September 2025 edition, it moved to 14th rank, then to 13th in October, and eventually to 16th in December 2025, and to 17th in the current edition.
The next efficiency point on the list is 22.8%, which in the current list corresponds to rank 18 and is shared by a solo company, SPIC with its BC module. Represented by 5 products in July 2024, the number at 22.8% efficiency reduced to 3 in November 2024 after Astronergy and JA Solar advanced to higher-efficiency groups. In July 2025, DMEGC’s move to the 23% class further reduced the count to 2. In this edition, Tongwei’s rise to the 4th position leaves SPIC as the sole representative at the 22.8% efficiency band. There has also been a steady decline in the band’s rank – from 9th in November 2024, to 10th in March 2025, 11th in May, 12th in June, 13th in July, and further down to 15th in September 2025. Some reshuffling at the top helped it improve to 14th rank in November 2025, but it dropped again to 17th in December 2025, given the adjustments in the listing above.
SPIC is the only occupant of the 22.8% efficiency level and 18th rank. The company lists its Andromeda 3.0 series BC module with 410 W power output. The product comprises n-type TOPCon-based BC (TBC) cells of 166 mm size that are cut in half.

The dimensions are 1,728 × 1,205 × 30 mm, and it weighs 22.7 kg. The product comes with a warranty of more than 92% power attenuation at the end of 25 years.
In July 2024, REC Group made a significant update to its product lineup by commercializing the new Alpha Pure-RX module. This module replaced its predecessor, the Alpha Pure-R series, in our listing. Designed with a foil-wire interconnection technology, the Alpha Pure-RX is significantly improved over its predecessor, which achieved up to 22.3% efficiency and a module power of 430 W. As a result of this advancement, REC’s ranking jumped from 27th to 12th and then a couple of places down to 14th in November. It slid to 15th in May 2025, to 16th in June, 2 places down to 18th in September, up a place to 17th in November, and to 20th in the December 2025 listing.
The next group of products with 22.5% efficiency is now represented by 2 companies – EGING PV and Runergy – at rank 22. Once a hotspot, this efficiency level saw the number of companies sharing this value considerably reduced over time, from 7 to 6 in July 2024, with the collective ranking slipping from 15th to 16th in November 2024. In May 2025, Trinasolar’s advancement to the higher 23% efficiency band further reduced the count to 5, leading to another drop in the group ranking to 17th. In June, the group’s position slipped further to 19th. In September 2025, DAS Solar’s improvement reduced the number of companies to 4, with the group ranked 21st. In the October 2025 edition, following Canadian Solar’s efficiency improvement to 22.6%, the number of companies in the 22.5% band further decreased to 3, and the collective group ranked 22nd. In November 2025, following Maxeon’s product delisting, the group’s rank rose to 21st. With Risen Energy’s efficiency update in December 2025, the group's members were reduced to only 2 – EGING PV and Runergy – and their rank dropped to 22nd, which remains unchanged in February 2026.
The EG-580NT72-HL/BF-DG PV product from EGING PV, part of its STAR Pro series, has a rated module efficiency of 22.5% and a power output of 580 W.

Runergy, a major Chinese cell manufacturer that expanded into module production, had both its TOPCon and PERC products featured in the listing for the first time in July 2023. The current TOPCon module, initially listed with an efficiency of 22.4% until November 2023, was upgraded to 22.5% in December, resulting in a significant jump from 21st to 10th place. The ranking gradually declined thereafter, dropping to 12th in April 2024, 14th in July, and to 17th in November 2024. It then moved down to 19th in June 2025, to 21st in September, to 22nd in October, and improved to 21st in November 2025. Due to the efficiency updates above, it dropped to 22nd in December 2025, where it currently remains.
URECO is a manufacturer formed from the merger of 3 leading Taiwanese cell manufacturers – Neo Solar Power, Gintech, and Solartech. The company offered products based on all 3 mainstream cell technologies – PERC, TOPCon, and HJT. While its PERC products were already part of our earlier listing, the modules based on the 2 remaining advanced cell technologies were included in our August 2023 edition. In January 2026, both PERC and HJT products were delisted, as the product datasheets and commercialization information are not available on its website anymore.
Currently, the company ranks 24th with its GLORY series FBF580B8D TOPCon module, with a rated efficiency of 22.45%. Following the delisting of Qn-SOLAR in October 2025, this module is now the sole representative of the 22.45% efficiency level, once represented by 4 companies.
In January 2026, the collective rank of the TOPCon products from Yingli Solar and Suntech improved from 26 to 25, where it currently remains. Since Yingli’s product has a higher power rating, it is listed first. Its YL625CF78 e/2 model from the PANDA 3.0 PRO 1 series has an efficiency of 22.4% and a power rating of 625 W. It is a bifacial dual-glass module comprising 156 half-cells based on the 182 mm wafer format. The module weighs 34.5 kg and measures 2,465 × 1,134 × 30 mm.
An early adopter of n-type wafer-based cell architectures, Yingli Solar entered the list in November 2023 with its PANDA 3.0 PRO TOPCon module rated at 22.36% efficiency and 625 W. In the August 2025 edition, its efficiency value was rounded up to 22.4% with no change in power rating, reclaiming its January rank of 27th. After Akcome’s delisting in January 2025, Yingli moved from 28th to 27th, but subsequent efficiency advancements by other manufacturers pushed it down to 29th in June. It briefly climbed back to 27th, slipped to 28th in September, and regained the 27th rank in the October 2025 edition. In January 2026, it was placed 25th due to the adjustments in the listing above. In addition, Yingli’s YLM 3.0 Plus 1 PERC module, first listed in February 2022, also adopted a new efficiency representation strategy – changing from 21.57% to 21.6% in August 2025. This product now holds the 32nd rank, one up from the previous month, due to the delisting of Suntech’s PERC module.
Suntech is the second occupant of the 25th rank, represented by its Ultra V Pro module series, which offers 22.4% efficiency and 605 W of power. This module replaced the 625 W Ultra V Pro Plus module in April 2024 and has remained unchanged since. While the predecessor featured 156 half-cells, the current module uses 132. Its efficiency, however, has remained unchanged at 22.4%, as have its other characteristics, including TOPCon cells and bifacial module technology. The module moved from 24th to 25th in October 2024, to 27th in June 2025, further down to 28th in September 2025, back to 27th in October 2025, and up another rank in the November 2025 edition, and was up to rank 25 in January, which remains unchanged in this edition. Another Suntech product, a PERC module first listed in July 2023, with an efficiency of 21.7% and ranking 32nd, has been delisted in this edition as the product is no longer available on the company’s website.

It utilizes M10 half-cut cell technology and uses 144 half-cell strips sliced from 182 mm cells. The product weighs 32 kg and measures 2,285 × 1,134 × 30 mm.
Kalyon PV, a Turkey-headquartered vertically integrated PV manufacturer from ingot to module, debuted in March 2024 with its TOPCon module at rank 24, dropped to 25th in July, and then to 26th in October. It moved down to 28th in the June 2025 edition, to 29th in August, to 30th in September 2025, and back to 29th in the October 2025 edition. Currently, the module ranks 27th in the listing, with 22.38% efficiency.
Qcells’ Q.TRON series TOPCon module slots in at rank 28, with 22.3% efficiency and 435 W power output. This 108-cell configuration is most likely based on the M10 wafer format, half-cell, and MBB module technology. The module uses a 3.2 mm glass on the front with a composite film at the rear. It weighs 21.2 kg and measures 1,722 x 1,134 x 30 mm.
The company re-entered our listing in February 2024 with its TOPCon Q.TRON SMART product, which was replaced by a higher-power Q.TRON variant the very next month. While its efficiency remains unchanged at 22.3%, this module delivers 35 W more than its predecessor. Interestingly, despite the power increase, the cell count has reduced from 120 to 108. This is only possible when adopting larger wafer formats. Qcells shared the 28th rank with GCL SI until May 2025. However, with the latter’s transition to a higher efficiency band in June 2025, Qcells’ module moved to an independent 30th position, followed by another move to 31st in September 2025. In the October 2025 edition, it regained its June position at 30th. It moved up a rank to 29th in November 2025 and is currently placed 28th.
CECEP Solar Technology is ranked 29th, with unchanged product specs: 22.1% efficiency and a 570 and 570 W power rating. The Chinese cell and module producer was founded in 2010, and has operating capacities of around 4 GW for cells and 8 GW for modules, according to its website. The currently featured TOPCon bifacial solar module is part of the company’s High Efficiency series, comprising 144 half-cells based on M10 n-type wafers. The module measures 2,279 × 1,134 × 30 mm, features a 3.2 mm front glass, weighs 32.6 kg, and offers a linear power warranty similar to that of other TOPCon products. Although the module’s specifications have not changed, shifts in ranking among higher-efficiency modules have affected its placement in the overall list. After moving from 30th to 31st in June 2025 and then to 32nd in September 2025, the module returned to 31st in October 2025. Its rank further improved to 30th in November 2025 and now to 29th in this edition.
Below 22% Efficiency Group
The remaining 11 products on the list have efficiencies below 22%, of which the bulk, or 9, are PERC modules, while the remaining 2 are HJT-based. The number of PERC modules has been declining recently. In July 2024, Kalyon PV’s PERC module was delisted, followed by Tongwei Solar’s product in September. In October 2024, a module each from Astronergy and Talesun was delisted, while JinkoSolar’s module was delisted in December. In total, 5 PERC modules were delisted over H2 2024. In January 2025, 2 PERC modules were delisted, one each from Akcome and Risen Energy. In July 2025, EGING PV’s PERC module was removed from our listing, as its datasheet was no longer available on the company’s website. With JA Solar’s delisting of its PERC product in October 2025, DAS Solar’s PERC module in November 2025, and GCL SI and Canadian Solar’s PERC modules in December 2025, the count of PERC products dropped to 13. Further, delisting from LONGi, Trinasolar, and URECO in January 2026, the count significantly dropped to 10 in a month. With Suntech’s PERC product phase-out, the current product count is brought down to 9.
As mentioned above, 2 non-PERC products are listed with less than 22%, and both are based on HJT. One of them is Jinergy’s HJT module, JNHM144-475, which ranks 30th, rated at 22.85% efficiency and 475 W. It is a dual-glass bifacial module with 144 half-cells based on 166 mm wafers. The module measures 2,094 × 1,038 × 30 mm and offers a bifaciality of over 85%.
The current product was updated in September 2023. Its efficiency of 21.85% is 0.17 percentage points higher than its predecessor. The featured JNHM144-475 model is slightly larger than the previous one, with 144 cells, and thus boasts a higher power rating of 475 W.
The other HJT product is from Meyer Burger, currently ranked 31st. The product has not undergone any changes from its current specification of 21.8% efficiency and 390 W module power.
Several module series available today have efficiencies slightly exceeding 21.5%, as high-efficiency cell architectures are not a prerequisite for reaching that level. However, in order to design products beyond 21.7%, cell technology is key.
While we did observe an increase in the number of companies achieving module efficiencies of up to 21.7% with PERC, the representation eventually narrowed to a single product, Suntech’s PERC with 21.7% efficiency and 560 W power, which is now delisted in this edition.
LONGi and Risen were part of this group until November 2022. Canadian Solar joined the list of 21.7% efficiency PERC modules in January 2023, Tongwei in February, DAS Solar in April, and Suntech in July 2023. However, Tongwei’s PERC module with shingled technology was delisted in September 2024, reducing the number of companies sharing the rank at the time from 6 to 5. In the January 2025 edition, Risen Energy discontinued its PERC module, prompting its delisting, and further reducing the number of companies to 4. With the delisting of PERC products from DAS Solar in November and from Canadian Solar in December 2025, the 21.7% efficiency group's representation further dropped to 2 companies – LONGi and Suntech.
The next efficiency level is 21.6%, which was also represented by 2 companies until December 2025 – Trina and Yingli – and is now represented by only Yingli, ranked a place up at 32nd with the phase-out of Suntech’s PERC module. In the October 2025 edition, with the delisting of JA Solar’s PERC module, this efficiency band was jointly represented by GCL SI, Trinasolar, and Yingli Solar’s PERC products, ranking 38th. In November, this trio ranked a joint 36th. All 3 modules shared a power rating of 670 W, featuring 132 G12-size half-cells. With the details of GCL SI’s PERC product no longer available on its website, the product has been delisted, and the group, comprising Trinasolar and Yingli, was placed 35th in December 2025 and at 33rd in January 2026, with the delisting of PERC products from LONGi and Trinasolar.
The 21.57% level is represented by 5 companies, all ranked 33rd, up from 34th previously. All these products moved down a position to 42nd in August, to 43rd in September 2025, again to 41st in October 2025, and to 39th position in November 2025. With the 2 PERC products delisted as mentioned above, the group’s ranking improved to 37th in December 2025, then to 34th in January 2026. Jinergy, Qn-SOLAR, Seraphim, SolarSpace, and ZNSHINE are the combined owners of this position. All products of these companies are built with 132 half-cells of the 210 mm wafer format interconnected with MBB. Not just efficiency of 21.57%, these 5 products have the same rated power of 670 W due to the same wafer format and the number of half-cell strips.
The lowest efficiency of 21.5%, which is also the minimum threshold for inclusion in this list, is currently represented by 3 products at rank 39, 4 steps up from 43rd previously – Runergy, CECEP, and Qcells.
In the May 2025 edition, Qcells introduced an update with a new high-power PERC module rated at 600 W, replacing its earlier 590 W version. While the efficiency remains unchanged at 21.5%, the already higher power compared to its peers’ 555 W positions Qcells ahead of Runergy within this group, following the methodology of highest power first, and alphabetical order, if equal.
Summary
The second monthly edition of TaiyangNews’ TOP SOLAR MODULES this year features 40 high-efficiency products from 33 companies, down by one entry compared to the previous month. While the overall list has slightly contracted, this edition records fresh efficiency updates among leading TOPCon suppliers.
JA Solar and Tongwei Solar have both confirmed the commercialization of their 23.7% efficiency TOPCon modules. These updates move both companies into a shared 4th position in the ranking, alongside Trinasolar. As a result, ranking positions below have shifted, including Huasun’s HJT product, which moves from 7th place in the previous edition to 9th in the current listing.
At the same time, the gradual exit of PERC technology continues. Suntech’s PERC product has been delisted following its phase-out, contributing to a reduction in total listed entries. These developments have led to ranking adjustments between positions 4 and 19, as well as between ranks 32 and 38, while the top 3 positions remain unchanged from the previous edition.
Overall, this month’s update highlights ongoing efficiency improvements within TOPCon technology alongside the continued contraction of PERC offerings in the high-efficiency segment.
